To all whom it rmty concern:

Be it known that 1, LEWIS WnnsnL An co'r'r,

of Worthington, county of Nobles, State of 3 Minnesota, have made certain new and use ful Improvements in Heating and Ventilating Systems, of which the following is a specification.

and inexpensive device that can be applied in connection with an ordinary heating-stove for taking alarge amount of fresh air from the outside of the building and properly heating the'same and distributing it to the room also take a part of the cold air from the lower part of the room and conduct it to the smokestack or chimney.

In the accom ianying drawings, forming part of this speeiiication, Figure l is a section of a portion of a room, showing my heating and ventilating system arranged therein.

Fig. 2 is a horizontal section on line 2 2 of Fig. 1. Fig. 3 .is a vertical section on line 3 3 of Fig. 1.

In the drawmgs, 2 represents-"a stove or heater of ordinary construction. This heater is provided with the usual fuel-door 3, with a heating-drum 4, and with a smokepipe 5,leading to the chimney 6. The opening into the chimney is preferably located near the ceiling 7 of the room to be heated. Surrounding the stove 2 is a sheet metal drum 8, preferably open both at top and bottom and supported at a suitable distance above the floor 9 by the legs 10. This drum is provided with a suitable door 11, through which fuel may be supplied to the opening covered by the door 3 of the stove. Arranged within this drum and nearly surrounding the lower part of the stove is the conveyer 12, of nearly circular form and provided upon its inner wall with a series of openings 13. A pipe 14 leads from outside of the building and connects with the conductor 12. By this means a supply of fresh air from the outside atmosphere is brought in through the pipe lei and carried in the conductor 12 substantially around the stove, and it escapes through all of the openings 13 and passes upward between the interior of the drum 8 and the eX- terior of the stovc and enters the room. By

this means a large supply of fresh warm air provided. V

For the purpose of simultaneously taking away a portion of the cold foul air that collocts near the floor of the room 1 prov de a drum 1?), surrounding the smolu pipe 5 near the point where it enters the chimney.- iho pipe .16, of larger diameter than the pipe connects the drum with the chimney, and in this pipe I provide a series of supports 17 for holding th. pipe centrally within the pi pc 16. A pipe 18,1.avingan open .lowercnd supported, preferably, upon suitable legs 19, extends from a point near the surface of the drum and connects with the drum 15. By this means the cold foul air is taken up from a point within a few/inches of the iloor of the room and is carried upward through the pipe 18,- the drum 15, and the )ipc 16 into the chimney. By placing the rum 15 near the ceiling, where-the air is warm, and having the s1nol e-pipe from the stove pasliwhrough it the air in this drum will be h .ted and a strong draft through the pipe 18 will be created. The drum 8,"surrounding the stove, prevents overheating persons or objects near the stove and directs fresh air brought in from outside the building through the pi 3c 14 upward along the surface of the stove, thereby causing said air to be heated to the proper temperature before escaping into the room or apartment to be heated.

It will be noted that with this system a large supply of fresh air is brought into the. room from the outside atmosphere, that this air is evenly distributed around the stove or heater by the conveyor 12, and that it is then thoroughly heated as it passes upward between said conveyor and the outer surface of the stove or heater and between the inner wall of the drum above said conveyor and the outer surface of the stove, and that when it enters the room or apartment to be heated it is at a high temperature and in this condition is distributed through the room.

It will also be noted that the cold foul air lying along the floor of the room drawn through the pipe 18 and conducted directly into the chimney. By this means 1 secure :1 u eflicient and economical heating system that can be inexpensively applied to any room or apartment that is to be heated.

T dismivantages arising from the heat- C e -i i) ing' oi a room by direct radiation from a stove or heater are done away With, the drum surthe stove prevents overheating in the vicinity of thestove byjdirecfi'radiation from its surface, and the arrangement for bringing the fresh air into the drum" and around the stove provides an adequate ventilation and aproper tempering of the air that is thus brought into the room,

This system is especially "adapted for schooioon'is that are heated by means of SL-OVSS or separate heaters for each room, Where a large number of-children are kept for derable period of time in. a single room. y such rooms are heated directly by ed no means for ventilation is pro- The air in'such instances becomes the health of the children is seriously effecwo. By my system the rooms are ade- "Lely heated and fullyfventilated. 'ihe system is also equally advantageous for churches or other auditoriums.

he system is also applicable for the heating of private residences or other buildings.

The constant circulation of air Within the room caused by the arrangelnent'of the heating-drumand foul-air flue equalizes the temperatureof the air in ali arts of the room. The layer orstratum of. ot air invariably found in the upper portion of all unventilated rooms is thus broken up and caused to mix with the other air of the room, and this,' together with the fact that the cold or foul air flue is constantly drawing "the cold and impure air from near the floor and discharging ceases it through thechimneygfineyrenders it possible to properly-heat a given room with much less fuel than it takes to heat the same room I by the old process of direct radiationwithout ventilation. 7

I have shown the f1'esh air pipe 14 Provided with a suitable valve or damper'14 and the foul-air pipe 18 provided Witha einiilar'valve or dam e1 18.

I claim as my inyention+. r

1. The combination; wi ha. heater, of a surrounding drum openat top andbottorn, a conductor arranged Within said: flex-- tending "around said heater and 'proyided with a series ofcpenings, upionits' inner sup- 30 face and a pi e leading from, the outside"at, inosphere an connected with said conductor, substantially as described. r I

2. The combination,, with a heater, of the drum 8 surrounding said heater and open at 5 5 top and bottom, the conductor 12 arranged upon the inner 'Wall of said drum. and extend ing horizontally around said heater, provided with a series of openings 13 upon its inner surfaceand the pipe 14 connected with said drum and adaptedto conduct air. from Y the outside atmosphereinto said conductor 12, substantially as described. 1 4 In Witness whereof I have hereunto set myhand this 13th day of April, 1906.
